Effects Of Stretching On Fascia

Helene Langevin is a professor at Harvard Medical School and at The University of Vermont College of Medicine. She is also the director for the Osher Center for Integrative Medicine. Her lab has conducted a lot of interesting research on connective tissue. I’ve summarised some of the findings that relate to the effects of stretching on connective tissue (fascia).

Studies from her lab have shown that stretching had beneficial effects on chronic inflammation in rats. They noted increases in stride length, decreased pain and decreased macrophages (inflammatory cells). Both active and passive stretching were effective and had an effect on acute and chronic phases of inflammation. Stretching decreases pro-inflammatory mediators and increases pro-resolving mediators such as Resolvin, which is synthesised from omega-3 fatty acids.

A thicker thoracolumbar fascia has been identified in some people with low back pain. And the decreased mobility of the fascial layers is thought to stem from adhesions between the layers. Stretching can decrease connective tissue adhesions (fibrosis) by decreasing collagen formation.

Additionally, links have been found between chronic inflammation, fibrosis and cancer. In summary, stretching can have beneficial effects on inflammation, pain, function and even the predisposition to certain types of cancer!
